Testimonials

"

My freediving has accelerated significantly in a short amount of time. Throughout my journey, crisp technique has been a top goal, and Twigy has strongly guided me in this area. From finning and arm pulls to no-fin kick cycles, I've seen consistent improvement in my form and technique through her video review and feedback, assessment of my time, distance, and depth results, and in-person coaching. She's patient and understanding, and she knows how to pivot her approach to ensure the teaching resonates.

I had an excellent experience training with Twiggy. Her passion and expertise made the course both engaging and rewarding. The knowledge and skills I gained continue to be valuable as I progress in my own training.

I am an experienced waterman: Surfing, Fishing, and Free Diving since the age of 12, however my personal best depth is shy of 60 feet. I have employed Twigy Fung for both a beach dive and boat dive in Cabo San Lucas. She was extremely helpful and informative on both dives. On the boat, we were in 1,200 feet of water diving with both Sea Lions and Dolphins simultaneously. Having an experienced diver like Twigy along brought calm to the situation making my group feel extremely comfortable and safe. I also witnessed her reach her (personal best at the time) free diving to the depth of 65m off the transom of my own boat out of Palm Beach, FL. Her devotion and strength toward this sport is highly evident.

I was feeling stuck and knew I needed some coaching to get over a hurdle, and I just happened to come across an opportunity to train with Twigy. Twigy was knowledgeable, helped me identify points of struggle and gave me drills to work on immediately. In the water, she made me feel confident, safe and organized. I was able to meet my goals and obtain knowledge to take with me moving forward. LOVED the experience and can't wait for more!!

I've been training with Twigy and couldn't recommend her enough as a freediving coach. I've seen huge improvements in a short time: (7 meters more in depth in just one week), improved pool PBs, and a noticeable increase in my strength and overall performance. She's especially great with equalization, but what I value most is the calm and trusting environment she creates. You can focus on enjoying your dive and progress without stress or pressure.

Twigy Feng is a competitive freediver, AIDA-certified safety diver, and Molchanovs Wave 2 instructor based in Orlando, Florida. She has served as in-water safety and rescue for depth and pool competitions across multiple countries — including Costa Rica's AIDA Champion Cup, the Nicaragua Apoyo Competition, and the first-ever ice diving event held in the United States — and currently ranks #5 among female depth athletes in the USA.

Off the line, she serves as an ambassador for The Only One, a marine conservation NGO, promoting sustainable ocean practices alongside her competition work. Mazu Freediving carries that same dual commitment: building strong, safe divers while protecting the ocean they train in.

Why "Mazu"

In Chinese coastal tradition, Mazu is the sea goddess who calms storms and guides sailors safely home. It's a fitting namesake: staying calm under pressure and guiding people safely through deep water is exactly the work Twigy has built her career around — as an athlete, an instructor, and a safety diver standing by at the world's most demanding competitions.
